This huge sunspot group named AR2396 is over 150,000kms in diameter and the dark core is now three times the size of our Earth, image was taken on the 8th August 2015. The image was taken with a Meade 80mm refractor telescope fitted with an Orion glass solar filter. I used a Canon 700D camera with a 2x and 3x Barlow lens attached, the exposure time was 1/640th second and ISO 200. There were 25 images stacked in RegiStak6 and then processed in PS CS4.
